Real CRON set up .

Hi,

I thought this would be the bast place to get some doubts cleared.
Here’s my question.

if ( !wp_next_scheduled('my_task_hook') ) {
    wp_schedule_event( time(), 'hourly', 'my_task_hook' );
}

function my_task_function() {
     wp_mail('[email protected]', 'Automatic mail', 'Hello, this is an automatically scheduled email from WordPress.');
}
add_action('my_task_hook', 'my_task_function');

The above code is to schedule a cron task hourly.
Then i use

/usr/bin/wget -O - -q -t 1 https://www.yourdomain.com/wp-cron.php

and set it in plesk to run it every hour.
I have also wrote define(‘DISABLE_WP_CRON’, true) in my wp-config.php
My actual question here is :
Do i have to set the wget command to run every hour , if i’m setting the schedule as hourly in my wordpress code .??
Similarly , if i have to run the wget command every day( daily) , do i need to set the worpress cron fuction as wp_schedule_event( time(), ‘daily’, ‘my_task_hook’ )??

Regards
